Extreme weather events drive
up the numbers
Several new climate records were set in 2016.
As data from previous years shows, climate and
weather-related disasters regularly account for
most of the global total (see figure 1.14). In 2016,
they were responsible for 23.5 million displacements, or 97 per cent of all disaster-related
displacements. All of the 10 largest disaster
displacement events in absolute terms were
weather-related.
Flood disasters tend to make up the majority
of climate and weather-related displacements
each year. In 2016, however, storms caused 12.9
million displacements worldwide – 55 per cent of
all weather-related disasters – by triggering mass
displacement of populations living in exposed
and vulnerable coastal areas. Seven of the 10
largest displacement events of 2016 were stormrelated, and nine out of 10 relative to population
size (see figure 1.15).
The number of new climate and weather-related
disaster displacements in 2016 was above the
annual average since 2008 of 21.7 million, but
displacements associated with geophysical
hazards were well below average, with approximately 700,000 displacements recorded in
2016. Excluding 2008 as a highly unusual year
because of the Sichuan earthquake disaster in
China, disasters triggered by geophysical hazards
have caused an average of around two million
displacements a year.
Despite the lower than usual figure, there were
still some significant earthquake disasters in 2016
that were followed by prolonged displacement
and increasing vulnerability for those affected.
A 7.8 magnitude earthquake and strong aftershocks struck the Manabí and Esmeraldas provinces of Ecuador on 16 April, killing more than
600 people, displacing at least 259,000 and
leaving some towns needing to be permanently
relocated.78
On the same day on the other side of the Pacific,
a 7.3 magnitude earthquake displaced at least
196,000 people in and around Kumamoto in
the southern Japanese prefecture of Kyushu.79
One year on, more than 47,000 people who lost
their homes are still displaced.80 Health problems
brought on or worsened by prolonged displacement, especially among older people, caused
more deaths than the direct impacts of the earthquake, such as collapsing buildings. Out of 170
indirect deaths reported, 90 per cent were of
people over the age of 60.81
